SPLICE-BAR FOR RAIL-JOINTS.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application tiled May 23, 1907. Serial No. 375,339.

To all w7wm it may concern:

Be it known that we, lVILLiAii l. Tnonsort, of Philadelphia, in the countyofPhila- 14 are side views; Figs, l5, l6, 18, 21 are delphia and State of Pennsylvania, and SAu- UEL G. THoMsoN, of Buffalo, Erie county State of New York, have invented anew and useful Splice-Bar for Rail-Joints of which side views of splice bars embodyin our invention; Fig. 17 IS an end view 0 the bar shown in Fig. 16; Fig. 19 is an end view of I the bar shown in Fig. 18; Fig. 20 is atop plan view of the bar shown in Fig. 18; and Fig. 22 is an end view' of the bar shown in Fig. 21;

The object of our invention is to reduce to a minimum the amount of metal necessary to secure a maximum degree of vertical and lateral stiffness in a splice bar for rails, and at the same time to provide vertical bolting faces adjacent to. the bolting holes through these bars, without making the metal at the bolt holes comparatively thicker than between the bolt -holes.

Our invention consists essentially in displacing a portion of the bar or plate from its form as riginally rolled, in sucli a. manner that the isplaced portion will serve either as a decided reinforcement without the use of additional metal, or will convert a portion of the bar which did notoriginally stand in a vertical position into a section which will afford vertical bolting faces adjacent to the bolt holes-through the bar. The principle involved is the same in both cases. In the case of a rolled angle bar having originally a vertical bolting face. certain portions between the bolt holes may be forced outward in such a manner as to afford a bulging reinforcement for the bar which will not interfere with the turning of the nuts on the vertical bolting faces lying between two of such reinforcements. ln incase of a bar whose upper men'xber is not face, a portion of the bar adjacent to the bolt hole may be displaced to provide a vertical bolting face. While these operations preferably involve the stretching of the metal forming the sides of the portion thus displaced. this stretching is not essential to the application of our invention, as the metal may be forced out of position in such an ab rupt manner that it will be cut loose from the bar atone or m'orepoints and at ,the'

same time provide for a material reinforcement for a vertical .boltmg face.

The invention is also applicable for the same purpose and with the same conserva-.

tion in the amount of metal involved to splice bars having extensions below the base of the rail, in which theobject to be attained may be either to afford material reinforcement without the use of j additional metal or to provide vertical bolting faces adjacent to such bolt holes as it may be desirable to.

place in the depending portion or flange.

The invention may also be applied to sections of that portion of the bar which are adjacent to the under side of the head of the rail, without necesr arily reducing the top bearing surface of the bar under the head. Portions of the metal may likewise be forced either inward or outward, according IO the original conformation of that portion of the bar, the object in all cases being to secure a stronger or more efiicient'bar with the use of a minimum amount of metal and at the same time provide vertical gripping faces for bolts. r

. The preferable application'of our invcntion is to roll a freely depending flange splice bar, the upper portion of which does not have a vertical bolting face, and then forge a portion of the web. adjacent to the bolt holes, to secure a vertical bolting face with out the use of auxiliary parts.

Fig. 1 shows a splice bar having a portion ,11 forged to form a vertical seating face for the nut. and also aportion 12. displ -lced to provide spiking facilities and additional lateral stiffness.

Fig. 2 ."aows a bar'having an inward displacdmont 13. between adjacent bolt holes.

In the bar shown in Fig. 3. there is a diagonal displacement H between adjacmu holt holes. and also a dmvnward displacement 15 of a portion or portions of the base. mem

ber 10.

lUT;

Fig. 4 shows a lateral displacement 17- f the upper member of the bar and an upward displacement 18 of" a portion of the depending member in contact with the under side of the base of the rail.

Figs. and-6 show bars having depending-portions 21 between the ties, and with the upper members having inclined faces '22,

'. ping ace for the be t in combination with reinforcing diagonal web portions between the bolt holes andalsd a diagonal displacement 27 of the depending member.

Figs. 9 and 10.1llustrate splice bars having depending members whichare connected by bolts below the base of the rail, portions 28 of said members being displaced .in-

wardly to provide vertical-bolting faces. This displacement may, as shown at the right-hand side of Fig. 9, separate a portion thereof from the remaining metal.

The bar shown in Figs. 11 and 12 has the depending portions of its splice bar pro- V1 ed with inward displacements 29 or 30,:

to provide the vertical bolting seats. Figs. 13 and 14. illustrate another wayof obtaining the same result, one of the bars having an inward displacement 31, which is separated at the top and sides from the adjacent metal.

Figs. 15 to-22 illustrate various ways in which a splice bar having curved or inclined outer .faces may be displaced so as to form vertical bolting faces, or reinforcements, or both, and will be readily understood'without detailed description. In each of these figures, the numeral 32 indicates a displacement of the metal.

It is evident from our drawings that a displaced portion may be cut loose from the bar along one side of said displaced portion and be joined to the bar by gussets along all or parts of the other sides of said displaced portion; this is shown in Figs. 5, 6, 9, 10, 13, 14, 21 and 22, where the displaced metal is forced abruptly inward along one side of this displaced portion to such a great distance-that themetal can not be stretched into a gusset and is thus cut loose entirely where the displacement has been greatest,

but the remaining sides of the displaced portion are not displaced so far'that they will cut loose and therefore they remain in the form of gussets.

having a boltin From the foregoing, the wide application of our invention, together with the advantages thereof, will be readily understood and appreciated by those skilled inthe art. Inclined, as used in the claims, is to be understood as meaning straight or curved inclined, or a combination of both. 'It will also be understood that our invention is applicable to splice. bars withoutdepending flanges, as well as to bars having such flanges.
